Thanks Doug and Jonathan for the CIImage suggestion, I'll take a closer look.
But one thing I don't see at all in CIImage.h is how to get an NSData of the
pixels of a CIImage. There are init methods that take NSData, but nothing I
see gives NSData.
I should note that I have no need to draw this data whatsoever. I only need
access to the raw pixels to do some custom processing on.
Cheers,
